ROTATING SELF-CLOSING CASE FOR PANTRY-SLIDES.

SPECIFICATION forming part of Letters Patent No. 416,146, dated November 26, 1889.

Application filed May 13, 1889. Serial No. 310,653. (No model.)

To all whom it may concern.-

Be it known that I, NEHEMIAH S. WOOD, of Chelsea, in the county of Suffolk and State of Massachusetts, have in vented certain new and useful Improvements in Rotating Self-Closing. Cases for Pantry-Slides, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to so construct a casing and case for pantry and dining-room use that at no time will there be an open communication between the two rooms between which the device is placed, the case being made to revolve by the attendant and having two self-closing doors so arranged in connection with an automatic device that one of the doors shall be closed while the other is open. This object I attain by the mechanism shown in the accompanying drawings, in

' which-- Figure 1 is a vertical section showing the casing and case and their connected parts.

one of the doors, and a part of the upper casing. Fig. 4. is a horizontal section taken on line y 3 of Fig. 1.

In the drawings, A represents a part of the fixed casing or wood-work in which my rotating case 0 is placed.

B is the base of the case, and it rotates on a pivot Z). (See Fig. 1.) The base 13 has cords H H, working in grooves about it, as shown in Figs. 1 and 4. Each of the cords H H terminate in handles or knobs K K, by means of which the attendant can, by drawing the cords, cause the case 0 to rotate.

The cords H H are arranged to draw about friction-pulleys L L, Fig. 4, so as to be easily moved and not to be worn by friction.

The case 0 has but one opening 0 c, Fig. 2, through which dishes and other articles may be placed in the case or taken from it.

D and D, Fig. 2, represent doors which are curved in horizontal sect-ions, so as to be adapted to slide around on the curved track is in conjunction with the opening 0 c in the rotating case 0 will not be closed, its door D being in the position shown in Fig. 2, but the door D will be in position to close the Opening a a in the fixed casing.

My device for causing-the doors D and D to move at times as desired I will now explain. On the outside of the rotating case 0, Figs. 2 and 3, I have a catch-plate H having a notch H, (see Fig. 3,) which may catch on to the post M, that extends from the interior of the doors. The catch-plate H is attached to a sliding rod H which is held in place by the brackets H H At the top of the rod H a lever K is pivoted by the pin h. This lever K is pivoted at K,which acts as a fulcrum for it. The end of the lever K is bent, as shown at K and is adapted to be acted upon by fixed cam-pieces, one of which is shown at L Fig. 3. The cam-pieces L are attached to the upper part of the casing and are located near the door-post A A.

The operation of my device is as follows: If we suppose the rotating case 0 to be in the position shown in Fig. 2, with the door D open, and we wish to pass some article through from one room to another, the article is placed in the case 0. Now the attendant pulls upon one of the cords H, (in this case the one attached to K or K so as to cause the case to rotate in the direction of the arrow S, Figs. 2 and 4. This action will, acting through the Stud M and catch-plate 11, cause the door D to slide around until it closes the opening a a, Fig. 2. At the time that the door D has fully closed the Opening a c. the end K of the lever K will have come in contact with the fixed cam L (see Fig. 3) and will be depressed, thus lifting, through the rod H the catch-plate H and freeing it from the stud M on the doorD. Now the door D stops and a continued movement of the rotating caseC brings the other catch-plate in connection with the stud M, Fig 2, on the door D, and a still further motion of the rotating case 0 will cause the door D to open and at the same time bring the opening 0 c of the rotating case 0 in junction with the opening a a of the fixed casing, so that the article in the rotating caseO may be taken out. Byreversing these-operations the position of the rotating casing O and the doors may be restored to their place, as shown in Fig. 2.

I claim In a rotating self-closing case for pantry slides, the combination of the rotating case 0, partially inclosed within an outer fixed casing'and'having an opening 0 c and catchplates H H on its outer surface, and base B, having operating-cords H H, as described,

with the outer casing A,' d0ors sD,:locate'd ;in

--said outer. casing, each of said doors having a stud lvLupon it adapted .to engagewith the catch-plates 1-1 H substantially as and for I 5
